Why is my dog breathing fast after surgery? Is it pain or serious?
I agree that this is a pretty rapid respiratory rate for Daisy, particularly if she's resting while breathing this quickly. As you mentioned, it's very possible that this fast breathing is due to post-operative pain. However, if she's currently receiving pain medication after surgery, it's a bit less likely. Other causes of rapid breathing can include stress or anxiety, blood clots in the lungs, heart disease, pneumonia, among others. Regardless, it would be best to take Daisy to the vet urgently for evaluation. If the vet suspects pain as the cause, they will be able to prescribe additional pain medications. Otherwise, they will be able to perform any necessary diagnostic testing, which may include chest x-rays or blood clotting times to try to get to the bottom of this issue. I hope that everything goes well for Daisy!
